CROSS REFERENCE TO RELATED APPLICATIONS

This application is a National Phase Entry of PCT International Application No. PCT/KR2019/008458, which was filed on Jul. 10, 2019, and claims a priority to Korean Patent Application No. 10-2018-0081905, which was filed on Jul. 13, 2018, the contents of which are incorporated herein by reference.

TECHNICAL FIELD

Embodiments disclosed in the present disclosure relate to a method for tracking a position of an access point and an electronic device therefor.

BACKGROUND ART

With the spread of mobile devices capable of recognizing positions, various position-based services are being provided. For example, the mobile device may obtain its position information based on a global navigation satellite system (GNSS). Since GPS-based positioning is performed based on satellite signals, it may be difficult to accurately measure the position of the mobile device indoors.

Various methods are being studied to supplement the limitations of GPS-based position-based services and perform more accurate positioning. For example, the positioning of the mobile device may be performed using a signal transmission device having a fixed position. The mobile device may obtain a wireless fingerprint (e.g., information on a beacon, access point (AP), or cell), and transmit the obtained wireless fingerprint information to an external electronic device (e.g., a server). For example, an external electronic device receiving the wireless fingerprint from the mobile device may estimate the position of the mobile device by using a database associated with the wireless fingerprint.

DISCLOSURE OF THE INVENTION Technical Problem

In estimating the position of a mobile device based on the wireless fingerprint, it may be required to maintain and manage an accurate database. For example, the position of the mobile device may be estimated based on AP (e.g., WiFi AP) information. With the widespread of APs, a plurality of APs may be located in a small area. Therefore, positioning of the mobile device may be performed by using AP information without a separate device such as a Bluetooth beacon. In this case, a database including AP information and information on the associated position may be managed by an external electronic device. In addition, in order to manage a large number of APs, the external electronic device may manage the database based on crowd sourcing.

Since the AP is an electronic device having a relatively small size, the position of the AP may be easily changed. In addition, APs may be added or removed. In this case, a discrepancy may occur between the position information of the AP in the database of the external electronic device and the actual position. Furthermore, the accuracy of position estimation based on the wireless fingerprint including AP information may be reduced.

Technical Solution

Accordingly, an aspect of the present disclosure is to provide an electronic device including a memory storing identifiers of a plurality of access points (APs) and position information associated with the plurality of APs, at least one communication circuit, and at least one processor operatively connected with the memory and the at least one communication circuit, in which the at least one processor is configured to receive an AP list including information on a plurality of first APs using the communication circuit, obtain a representative position corresponding to at least a portion of the plurality of first APs based on positions corresponding to the plurality of first APs stored in the memory, and update position information of at least one second AP of the plurality of first APs stored in the memory based at least on the representative position if a position of the at least one second AP is a specified distance or more away from the representative position.

Another aspect of the present disclosure is to provide an electronic device including at least one communication circuit, at least one processor operatively connected with the at least one communication circuit, and a memory operatively connected with the at least one processor and storing identifiers of a plurality of access points (APs) and position information associated with the plurality of APs, in which the memory stores instructions that, when executed, cause the processor to receive an AP list including information on a plurality of first APs using the communication circuit, obtain a representative position corresponding to at least a portion of the plurality of first APs based on positions corresponding to the plurality of first APs stored in the memory, and update position information of at least one second AP of the plurality of first APs stored in the memory based at least on the representative position if a position of the at least one second AP is a specified distance or more away from the representative position.

Another aspect of the present disclosure is to provide an AP position update method of an electronic device, including receiving an AP list including information on a plurality of first APs, obtaining a representative position corresponding to at least a portion of the plurality of first APs based on positions corresponding to the plurality of first APs stored in a memory of the electronic device, and updating position information of at least one second AP of the plurality of first APs stored in the memory based at least on the representative position if a position of the at least one second AP is a specified distance or more away from the representative position.

According to various embodiments of the present disclosure, the communication circuit 390 may communicate with other external electronic devices (e.g., the first external electronic device 301, the second external electronic device 302, and/or the third external electronic device 303). For example, the communication circuit 390 may communicate with the first external electronic device 301, the second external electronic device 302, and/or the third external electronic device 303 via a second network (e.g., the second network 199 of FIG. 1 ). According to an embodiment of the present disclosure, the electronic device 201 may perform crowd sourcing of position information by receiving position associated information from various external electronic devices.

FIG. 4 illustrates an AP search environment 400 of the external electronic device 202 according to an embodiment of the present disclosure.

According to various embodiments of the present disclosure, the external electronic device 202 may perform an AP scan. For example, the external electronic device 202 may perform an AP scan based on a specified period, an arbitrary time, and/or a user input. For example, the external electronic device 202 may perform an AP scan by receiving information associated with the AP (e.g., an identifier of the AP) from each AP. According to an embodiment of the present disclosure, the external electronic device 202 may perform the AP scan by listening to a signal from the AP for a specified time.

According to various embodiments of the present disclosure, in the AP search environment 400, a first AP 421, a second AP 422, a third AP 423, a fourth AP 424, a fifth AP 425, and a sixth AP 426 may be positioned. According to an embodiment of the present disclosure, each AP may be assumed to have a substantially similar range of coverage. For example, each AP may be set to transmit a signal with a transmission power equal to or less than a specified transmission power due to communication environment regulations. According to an embodiment of the present disclosure, the external electronic device 202 may receive a signal from an AP positioned in a specified coverage 410. For example, the external electronic device 202 may receive signals from the first AP 421, the second AP 422, the third AP 423, the fourth AP 424, and the fifth AP 425, and may not receive the signal from the sixth AP 426. In this case, the external electronic device 202 may obtain AP information corresponding to the first AP 421, the second AP 422, the third AP 423, the fourth AP 424, and the fifth AP 425 through the AP scan.

According to various embodiments of the present disclosure, the external electronic device 202 may transmit, to the electronic device 201, AP list information 430 (e.g., position information report 203 of FIG. 2 ) including the AP information obtained through the AP scan. According to an embodiment of the present disclosure, the AP list information 430 may include AP information (e.g., an AP identifier) retrieved by the AP scan of the external electronic device 202. For example, the AP list information 430 may include AP information corresponding to each of the first AP 421, the second AP 422, the third AP 423, the fourth AP 424, and the fifth AP 425.

According to various embodiments of the present disclosure, the electronic device 201 may estimate the position of the external electronic device 202 based on at least a part of AP information included in the AP list information 430. For example, the electronic device 201 may assume that APs corresponding to the AP information included in the AP list information 430 have substantially the same distance as the external electronic device 202, and may estimate the position of the external electronic device 202 by using the position of the AP corresponding to the AP information stored in the database (e.g., the database 333 of FIG. 3 ). According to an embodiment of the present disclosure, the electronic device 201 may perform AP clustering on APs included in the AP list information 430, and may estimate the position of the external electronic device 202 by using the positions of the APs included in the AP cluster. For example, if the position of the fifth AP 425 is not included in the AP cluster, the electronic device 201 may estimate the position of the external electronic device 202 by using the first AP 421, the second AP 422, the third AP 423, and the fourth AP 424 excluding the position of the fifth AP 425.

According to various embodiments of the present disclosure, the electronic device 201 may perform clustering on APs corresponding to the AP information included in the AP list information 430. For example, the electronic device 201 may perform clustering only if the number of APs included in the AP list information 430 is equal to or greater than a specified number (e.g., a natural number equal to or greater than 3).

According to an embodiment of the present disclosure, the electronic device 201 may perform clustering based at least on positions of APs corresponding to AP information included in the AP list information 430. For example, clustering may be referred to as a procedure for finding one cluster having the highest AP density. For example, when the set of APs included in the AP list information 430 is C, a set C_(i) may be defined that includes, as elements, APs positioned within a specified distance d_(th) centered on the position of the i-th AP included in the AP list information 430 (for example, i is an integer equal to or greater than 1 and less than or equal to the number of APs included in the AP list information 430). For example, the set C_(i) may be defined as the following equation. C _(i) ={k|dist(i,k)≤d _(th) , ∀k ∈ C}   [Equation 1]

In the above equation, k may be an integer equal to or greater than 1 and less than or equal to the number of APs included in the AP list information 430, and dist(i, k) may mean a distance between the i-th AP and the k-th AP.

According to an embodiment of the present disclosure, the electronic device 201 may perform clustering by using, among the sets C_(i), the set C_(i) containing the largest number of APs. For example, the electronic device 201 may determine a set C_(i)* to be used for clustering according to the following equation.

$\begin{matrix} {i^{*} = {\underset{i}{argmax}{C_{i}}}} & \left\lbrack {{Equation}\mspace{14mu} 2} \right\rbrack \end{matrix}$

In the above equation, |C_(i)| may mean the size of the set C_(i). That is, the electronic device 201 may set the set C_(i) so that the number of APs included in the set is maximum.

According to various embodiments of the present disclosure, the electronic device 201 may determine the representative position of the cluster. According to an embodiment of the present disclosure, the electronic device 201 may obtain a position of an AP serving as the center of the cluster (i.e., the position of the i*-th AP) as a representative position of the cluster. According to an embodiment of the present disclosure, the electronic device 201 may obtain the representative position based on the positions of APs included in the cluster. For example, the electronic device 201 may set, as the representative position, a position with the shortest average distance, the highest correlation, or the lowest variance with the positions of APs included in the cluster. According to an embodiment of the present disclosure, the electronic device 201 may obtain the representative position based on the arithmetic average of positions of APs included in the cluster. For example, the electronic device 201 may determine the representative position x_(i)* of the cluster (e.g., set C_(i)*) according to the following equation.

$\begin{matrix} {x_{i^{*}} = {\frac{1}{C_{i^{*}}}{\sum\limits_{k \in C_{i^{*}}}x_{k}}}} & \left\lbrack {{Equation}\mspace{14mu} 3} \right\rbrack \end{matrix}$

In the above equation, x_(k) may mean the vectorized position of the k-th AP. Table 2 shows an exemplary form of x_(k).

TABLE 2 Position (latitude, k MAC address SSID longitude) 1 00:00:00:00:00:01 AP1 x₁ = {x_(lon1) x_(lat1)}^(T) 2 00:00:00:00:00:02 AP2 x₂ = {x_(lon2) x_(lat2)}^(T) 3 00:00:00:00:00:03 AP3 x₃ = {x_(lon3) x_(lat3)}^(T) 4 00:00:00:00:00:04 AP4 x₄ = {x_(lon4) x_(lat4)}^(T) 5 00:00:00:00:00:05 AP5 x₅ = {x_(lon5) x_(lat5)}^(T)

The setting method for the cluster (e.g., set C_(i)) and the representative position, which are described above, are exemplary, and embodiments of the present disclosure are not limited to the above setting method. According to an embodiment of the present disclosure, the electronic device 201 may simultaneously obtain the representative position and the cluster based on the positions of APs included in the AP list information 430. According to an embodiment of the present disclosure, the electronic device 201 may obtain the representative position based on the positions of APs included in the AP list information 430, and set the cluster centered on the obtained representative position. According to an embodiment of the present disclosure, the electronic device 201 may determine a cluster having the highest density of APs included in the AP list information 430 and obtain the representative position from the cluster. For example, the electronic device 201 may determine the density based on a ratio of APs in the cluster to all APs in the AP list information 430. For example, the electronic device 201 may determine the AP density of the cluster centered on the position of the i*-th AP according to the following equation.

$\begin{matrix} {\eta_{i^{*}} = \frac{C_{i^{*}}}{C}} & \left\lbrack {{Equation}\mspace{14mu} 4} \right\rbrack \end{matrix}$

For another example, the electronic device 201 may determine the AP density using a specified density estimation equation.

According to various embodiments of the present disclosure, the electronic device 201 may estimate the obtained representative position as the position of the external electronic device 202. For example, the electronic device 201 may transmit the representative position to the external electronic device 202 as the position information by using the communication circuit 390.

FIGS. 5A to 5G illustrate an AP cluster configuration of an electronic device according to various embodiments of the present disclosure.

In FIGS. 5A to 5G, the electronic device 201 is assumed to receive the AP list information 430 including the first AP 421, the second AP 422, the third AP 423, and the fourth AP 424, and the fifth AP 425 of FIG. 4 from the external electronic device 202.

Referring to FIG. 5A, for example, in a database (e.g., the database 333 of FIG. 3 ) of the electronic device 201, the positions of APs included in the AP list information 430 may be stored as illustrated in FIG. 5A. For example, AP1 may indicate the position of the first AP 421 stored in the database 333, AP2 may indicate the position of the second AP 422 stored in the database 333, AP3 may indicate the position of the third AP 423 stored in the database 333, AP4 may indicate the position of the fourth AP 424 stored in the database 333, and AP5 may indicate the position of the fifth AP 425 stored in the database 333.

Referring to FIG. 5B, if AP1 is set as the representative position 501 of the cluster 503, two APs (AP1 and AP2) may be positioned in the cluster 503. Referring to FIG. 5C, if AP2 is set as the representative position 501 of the cluster 503, four APs (AP1, AP2, AP3, and AP4) may be positioned in the cluster 503. Referring to FIG. 5C, if AP2 is set as the representative position 501 of the cluster 503, four APs (AP1, AP2, AP3, and AP4) may be positioned in the cluster 503. Referring to FIG. 5D, if AP3 is set as the representative position 501 of the cluster 503, three (APs AP2, AP3, and AP4) may be positioned in the cluster 503. Referring to FIG. 5E, if AP4 is set as the representative position 501 of the cluster 503, three (APs AP2, AP3, and AP4) may be positioned in the cluster 503. Referring to FIG. 5F, if AP5 is set as the representative position 501 of the cluster 503, one AP (AP5) may be positioned in the cluster 503.

As illustrated in FIG. 5C, if the position of AP2 is set as the representative position 501, the largest number of APs may be positioned in the cluster 503. For example, as illustrated in FIG. 5C, the electronic device 201 may set the cluster 503 and set the position of AP2 as the representative position 501 of the cluster 503.

According to various embodiments of the present disclosure, the electronic device 201 may set the representative position based on the positions of APs included in the cluster 503. Referring to FIG. 5G, according to an embodiment of the present disclosure, the electronic device 201 may set the representative position 501 based on the positions of APs included in the cluster 503. For example, the electronic device 201 may determine the representative position 501 from an arithmetic average of positions of the APs included in the cluster 503.

Referring to FIG. 5G, according to an embodiment of the present disclosure, the electronic device 201 may set the cluster 503 based on the positions of APs included in the AP list information, and derive the representative position 501 from the cluster 503. According to an embodiment of the present disclosure, the electronic device 201 may determine the representative position 501 and the cluster 503 based on the positions of APs included in the AP list information.

FIG. 6A illustrates an AP position update 600 of the electronic device 100 according to various embodiments of the present disclosure.

Referring to FIG. 6A, it is assumed that the representative position 501 is set for the position of AP2 and the cluster 503 is set around the position of AP2 as in FIG. 5C. As described above, the setting of the representative position 501 and the cluster 503 of the electronic device 201 are not limited to the example of FIG. 6A.

According to various embodiments of the present disclosure, the electronic device 201 may update the AP position by using the representative position 501. For example, if there is at least one AP (e.g., AP5) not included in the cluster 503, the electronic device 201 may update the position of at least one AP stored in the database (e.g., the database 333 of FIG. 3 ) by using the representative position 501. According to an embodiment of the present disclosure, if the AP density of the cluster 503 is equal to or greater than a specified value, the electronic device 201 may update the position of at least one AP by using the representative position 501. For example, if more than half of the APs in the AP list information are included in the cluster 503, the electronic device 201 may update the position of at least one AP by using the representative position 501. The density is exemplary, and the AP position update condition of the embodiments of the present disclosure is not limited thereto. For example, if there is a specified AP (e.g., an AP having high reliability of the position) in the cluster 503, the position of at least one AP may be updated independently of the density.

According to an embodiment of the present disclosure, the electronic device 201 may update the position of at least one AP (e.g., AP5) not included in the cluster 503 at least by using the representative position 501. For example, the electronic device 201 may update the position x_(i) to x_(i)′ by using the specified weight a (0≤a<1) as in the following equation. x _(j) ^(y)←(1−α)x*+αx _(i)    [Equation 5]

In the above equation, x* may represent the representative position 501.

According to an embodiment of the present disclosure, the electronic device 201 may set the weight a based on the number of updates of the position of the AP. For example, the electronic device 201 may set the weight such that the value for the position of the AP decreases as the number of updates of the position of the AP in the database 333 increases. According to an embodiment of the present disclosure, the electronic device 201 may use the weight which has a fixed value.

According to an embodiment of the present disclosure, the electronic device 201 may store the number of updates of the position associated with each AP of the APs in the database 333. For example, the electronic device 201 may not use an AP having the number of updates of the position equal to or greater than a specified number to estimate the position of an external electronic device (e.g., the external electronic device 202 of FIG. 2 ).

FIG. 6B illustrates an AP position update 601 of the electronic device 100 according to various embodiments of the present disclosure.

According to an embodiment of the present disclosure, referring to FIG. 6B, the electronic device 201 may update the position of an AP included in the cluster 503. For example, the electronic device 201 may update the position of an AP in the cluster 503 that satisfies a specified condition. According to an embodiment of the present disclosure, if the AP density of the cluster 503 is equal to or greater than a specified value, the electronic device 201 may update the position of at least one AP included in the cluster 503 by using the representative position 501. For example, if more than half of the APs in the AP list information are included in the cluster 503, the electronic device 201 may update the position of at least one AP by using the representative position 501. The density is exemplary, and the AP position update condition of the embodiments of the present disclosure is not limited thereto. For example, if there is a specified AP (e.g., an AP having high reliability of the position) in the cluster 503, the position of at least one AP may be updated independently of the density.

According to an embodiment of the present disclosure, the electronic device 201 may update the position of at least one AP (e.g., AP1) included in the cluster 503 at least by using the representative position 501. For example, the electronic device 201 may update the position of an AP according to Equation 5 by using the specified weight a (0≤a<1). In the example of FIG. 6B, although the position of the first AP is shown to be updated, the electronic device 201 may update the positions of all APs AP1, AP3, and AP4 included in the cluster 503.

According to an embodiment of the present disclosure, a weight for updating the position of an AP included in the cluster 503 and a weight for updating the position of an AP not included in the cluster 503 may be different from each other. For example, the weight may be set based at least on a distance between the representative AP and the AP of which position is to be updated.

Referring to FIGS. 6A and 6B, the electronic device 201 may update the position of AP5 stored in the database 333 to the position of AP5′ by using the representative position 501. The methods for updating the AP position, which are described with reference to FIGS. 6A and 6B, are exemplary, and embodiments of the present disclosure are not limited thereto. According to an embodiment of the present disclosure, the electronic device 501 may perform the AP position update only if it is determined that the same AP has deviated from the cluster 503 associated with the AP list information more than a specified number.
